I noticed that you try to uncomment a region in a src block a # gets inserted!
#+BEGIN_SRC emacs-lisp ; test #+END_SRC If you select ; test and run uncomment-region you get this: #+BEGIN_SRC emacs-lisp # ; test #+END_SRC It also does that in Python. Any ideas why? -- Professor John Kitchin Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 @johnkitchin http://kitchingroup.cheme.cmu.edu
